Deep within an essay On the Art of Thinking for Oneself, Schopenhauer has four novels to recommend his readers. Of course, they are each in a different language... He also gives us objective, measurable standards to judge the artistic merit of a novel. Schopenhauer looks at how much a novel deals with the inner life -- the more it deals with the inner life of the protagonist, the more artistic a novel becomes because it’s the inner world that excites our interest - not the outer world of representation.
Schopenhauer’s recommended reading list:
1) Tristram Shandy by Laurence Sterne ()
2) Julie, ou la Nouvelle Héloïse by Jean-Jacques Rousseau ()
3) Wilhelm Meister’s Apprenticeship by Johann Wolfgang von Goethe ()
